In analogy with spatial multilayers, we put forward the idea of Herpin equivalence in temporal metamaterials characterized by step-like time variations of the constitutive parameters. We show that, at a given frequency, ...

The conditions of formation and properties of hybrid organic-inorganic composites based on epoxy polymer matrix and a mixture of magnetic and polymeric fillers are studied. Based on the study of physicochemical properti...

Water repellency related to organic matter (OM) of coatings along the earthworm burrows (EB) walls can facilitate preferential flow due to limiting the water exchange with the soil matrix. The objectives of this work wer...

The effects of post-deposition heat treatment on the microstructure and mechanical properties of boron nitride thin films deposited on 316L stainless steel substrates via radio frequency magnetron sputteringwere investig...

The paper studied the elemental composition of lead alloys of appendage stamps and seals of Middle Ages, and the influence of impurity elements in the alloy and conditions for long-term storage of monuments on the course...

Abstract Extracellular matrix (ECM) proteins play a crucial role in culturing muscle stem cells (MuSCs). However, there is a lack of extensive research on how each of these proteins influences proliferation and different...

In this research , microwave ray absorbing coating materials had been prepared which work within ( X - band ) frequency i.e 3 cm wavelength . The coating materials were prepared from a mixture of pigmented materials such...

Abstract The penetration of CaO–MgO–Al2O3–SiO2 (CMAS) is one of the most significant factors that induce the failure of air-plasma-sprayed thermal barrier coatings (APS TBCs). The direct penetration of CMAS changes...

We propose a radio frequency (RF) and visibly transparent composite metasurface design comprising newly developed transparent multilayer conductive coatings. Detailed experimental and theoretical analysis of the RF/visib...

ABSTRACT Tetracycline (TC) is a commonly prescribed broad‐spectrum antibiotic, and its widespread use together with its persistence in biological matrices, particularly urine, has raised serious concerns related to cli...

Para avaliar as estratégias de alimentação de bovinos em pastejo, quatro novilhas da raça Holandês Preto e Branco foram mantidas em uma pastagem de capim-mombaça (Panicum maximum Jacq.) com cinco alturas de dossel,...

This paper reports on miniaturized hydrogen sensing platforms, exploring several means of fabricating nano‐ structured films and evaluating their sensing characteris‐ tics. Palladium-sputtered nanoporous organosilica...

In this work the structure and corrosion behavior of quasicrystalline cast Al63Cu25Fe12 and Al63Co24Cu13 alloys in 5-% sodium chloride solution (рН 6.9–7.1) were investigated. The alloys were cooled at 5 К/s. The st...

This study explores the use of Plasma-Enhanced Chemical Vapor Deposition (PECVD) to apply coatings from six different organic precursors onto aluminum nanoparticles (Al NPs). The goal is to improve their energetic perfor...

Sulfide superionic conductors (e.g., argyrodite Li6PS5Cl, LPSCl) are extremely promising for all solid‐state batteries, but poor atmospheric stability and high interfacial reactivity limit widespread adoption. Coating ...

The kinetics of diffusion of interstitial elements on the example of diffusion saturation with boron and silicon iron- carbon matrix ( - iron) was considered . The layers of intermetallic Fe - B - Si are formed and grow ...

Abstract Photonic crystals are periodic structural materials that have an impact on the propagation properties of photons. Due to their excellent optical, electrical and magnetic properties, their advantages and potentia...

Absorption, scattering, and fluorescence are processes that increase with electric field intensity. The most prominent way to enhance electric field intensity is to use localized or propagating surface plasmon polaritons...
